Wooden pendant light

thingiverse

This pendant light has 29 laser-cut segments glued together in a cone shape, a 3D printed PLA ring frame and self-made 10-guage socket. A three-arm hang lamp support is optional. Wood material: 2.6-3mm thick plywood. Cut the 29 segments (adding an extra one for reserve) and lay them flat in an arc. Some segments have straight notches, others have bent ones. Use this property to find a tight fit. The ends should be loose-fitting because later we close the circle and it would be inconvenient to force or file them then. Apply wood glue only on the notches. Let it dry for an hour while 3D printing the big ring. The glue is elastic yet, so you can bend the cone and click it into place in the ring. Note that the ring has 29 straight sides too for a precise fit. Glue the end notches and the edges of the ring (also with wood glue). Place a properly sized pot on the cone to press and align it and let the glue set for hours. The 10-guage socket has three 3D printed parts, plus contacts. Cut a 3mm wide strip from 0.25mm brass plate, bend it into shape (must exactly follow the contact holder) and glue the ends with epoxy in the holder. Maybe it's not a bad idea to put the lamp in the socket while the epoxy cures because it holds the brass contacts precisely in place. Solder the mains cable on the brass plate at the "S".
